Level 1
Conservative screening on minimal inspection data, with no stress analysis — performed by an inspector or plant engineer. A pass means fit for service. A fail means escalate, not condemn.
Decide whether damaged equipment can stay in service — and prove it.
AccurAPM FFS evaluates in-service pressure vessels, piping, storage tanks, boiler components and fired heater tubes against API 579-1/ASME FFS-1, 2021 Edition. It implements Level 1 and Level 2 assessments in full across the damage types of Parts 3 through 14, and prepares the load cases and acceptance criteria a Level 3 numerical analysis needs. Every assessment returns a verdict, a reduced rating where one is required, a remaining life and a next inspection date — with the equations, clause references and reviewers recorded alongside.
Parts 3 through 14 of API 579-1/ASME FFS-1. Parts 1 and 2 govern scope, responsibilities and documentation, which the module applies throughout.
A higher level always overrides a lower one for the same flaw and inspection date, and both results stay in the record.
Conservative screening on minimal inspection data, with no stress analysis — performed by an inspector or plant engineer. A pass means fit for service. A fail means escalate, not condemn.
Detailed but still closed-form, requiring thickness profiles or full flaw characterisation — performed by a pressure-equipment engineer. Usually less conservative, and more permissive, than Level 1.
Numerical analysis by a specialist, used where Levels 1 and 2 fail or do not apply. AccurAPM exports the defined load case set and imports the linearised stress results; the FEA itself runs in your analysis package.
An FFS assessment is direct evidence about a component's condition, which makes it more informative than a generic damage-factor model. Where FFS establishes a remaining life shorter than the RBI-derived interval, the FFS result governs — and AccurAPM raises that conflict explicitly rather than letting the two subsystems disagree quietly.
Bring us a real flaw — metal loss, a crack-like indication, a dent, creep service — and we will walk through the assessment as AccurAPM performs it.
